In part 3 of this 4 part video, Erica Mason from the University of Missouri shows teachers how they can use algebra blocks to make the abstract concepts of multiplying terms concrete and easier to understand for all students. In this video, Erica uses Algebra Lab Gear manipulatives, and the work is based off of research by Tricia Strickland.

Moving to the abstract concepts can be challenging for many kids, but can be especially challenging for those students who struggle in math.
